` DUMB-BELL ANDTHE LIKE.

Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed March 27, 1908. Serial No. 423,529.

To all whom it may concern: 1

Be it known that I, ALAN CALVERT, a citizen of 'the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Dumb-Bell and the Like, of Which the following is a specification. i

My invention consists of an improvement in an exercising device of the order of a dumb bell, bar bell or ring Weight, the same embodying disks or plates and shot or the like, and means for holding the same, Whereby the device may be'primarily Weighted relatively to the capacity of the .one Who is exercising by the employment of the disks or plates, and then as there is a requirement of increased Weight, I provide for the same by` the employment of the shot or the like,-which is convenient in its nature and delicate in its adjustment, While the original adjustment due to the plates is not disturbed.

It also consists of a receptacle for said shot or like material, the same being attachable to the holder for said disks or plates adapting said members to produce a head of spherical shape, or comparatively so.

For the purpose of explaining my invention, the accompanying drawing illustrates a satisfactory reduction of the same to Vpractice, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described. l

Figure 1 represents a partial side elevation and partial longitudinal section of a dumb bell, to Which the description hereafter Will be limited. Fig. 2 represents a face view of a detached portion of the shell of the device. Figs. 3 and 4 represent sectionsy of other forms of the device on enlarged scales. Fig. 5 represents a section, on an enlarged scale, bf a portion of the Wall of the receptacle for the shot or like material, and of the closure for the inlet thereinto. i

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawing A designates a shell, which is somewhat hemispherical and `closed by the Wall B at What may be termed the diameter of the shell, the center of said Wall and the pole of the shell having passed therethrough the rodC, which is continuous of the handle D of the device, said pole being depressed forming the chamber E, in Which is seated the collar F, Which is provided with bolts or screws Gfor firmly securing the collar to said rod, the head H of said collar being adapted to conform to the curvature lof the adjacent surface of the shell, so as to form an unbroken curved continuity thereof.

The rod extends outside of the Wall B and has tted on the same the plates J, Which are of dishing form placed one on the other and of gradually reducing diametersnvhereby they, in a measure, produce a hemispherical-shaped body, and complete the spherical-shape of the head of the device, it being noticed that each end of the handle D is provided With such head.

The outer terminal of the rod C is threaded for the engagement of the nut K, Which enters the recess L in the outer plate J, so that the surface of the nut conforms to the curvature of said plate so as to form an unbroken continuity thereof, it being evident that owing to the collar F and the nut K, the plates J and shell A are firmly clamped togetherand connected with the rod C;

In theWall of J(he shell A is an opening M, which is occupied by the removable cap or stopper N, ywhereby When the latter is displaced access is had to the interior of the shell for supplying the same with shot or vother pellets or pieces of loose material proper for loading or Weighting the shell, shot being preferred, and it Will be the medium employed in the further description of the invention.

In order to secure the cap in position, the Wall of said opening M has slots I therein, and the cap is rovided with tongues Q, which are adapte to pass through said opening, While the body of the cap enters said opening M, so that when the ca is rotated. said tongues ride on the undersi e of the Wall of the opening M, and so lock the cap to the shell. In order to prevent improper return movement of the cap, and consequent displacement of the latter, the Wall of the opening M has a shoulder R, on Which are seated the springs S, which press outwardly on the cap, and so hold the latter on its seat, the effect of Which is evident. It Will noW be noticed that as many lplates J `are employed as may be necessary to impart primary Weight to the heads of the device in harmony With the capacity of the one vvhe is exercising, the removal of one or more of said plates still preserving somewhat the hemispherical form of the body produced by said plates.

As the exercising continues, it is necessary or desired te increase the `freight of the heads, for this purpose shot is introduced into the shells A to the reqnireiil amoiznt, this being accomplished to a delicate extent and in a mest convenient manner 'eithont disturbing1 the original adjustment of the heads duc to the plates J' employed.

If reqr'ired, the Weight ol shot in the shell may be increased to a farther extent, or the same may be reduced by removal of a desired ernennt of the same.

Referring to Fig. 3:#In lien of the dishing' plates (I, I may employ the Vflat plates J, Which are inclosed in a comparatively heini" spherical shell A, which is screwed to the shell A, said shell A receiving' the end of the rod C and having' a recess L to receive the nut K.

In Iiig. 1l, dat plates QI are shown, but the shell A is dispensed with, While said plates in both Figs. 3 and il produce the same resnlts as those shown in Fig'. l

It will be noticed that each plate J or J? has its recess L accord with the mit K, so that as a plate is removed, the exposed pla-tc :vill have its recess occupied by said mit, it being also seen that recess IQ conforms to said recess Ii, so that the said nut and the collar F may interchangeably occipy either recess, as desired.

Attention is directed to the fact that the rod C is inclosed by a sleeve C, 1which is secured to the Walls of the shell A, so that should said rod be removed, the opposite openings in said Walls through which said rod passes are closed from Wit-hin the shell, and so prevent the shot from escaping' from their place of occupation.

Having thus described my invention, what I claim as new and desire to secure by .Letters Patent, isr- 1. In an exercising device of the character stated, a combination of Weight-plates, a receptacle for loose-Weighting material, and

means for connecting said plates and receptacle With a carrier common to both.
